BRAKE-BEAM HANGER.

To all whom it may concern:

' Be it known that I, HARRY E. Donne, a citizen of the United States, residing in the city of St. Louis and Stateof Missouri, have invented certain new and use'ful'lmprovements in Brake-BeamiHangers, of which the following is a specification.

This inventionrelates to brake beam hang- Aers for railway'v cars, and its purpose is to Vprovide improved means for supporting the usual brake beam from the car truck.

The principal'object ofthe invention is toprovide an improvedA brake hanger construction which will permit' the desired movement of the brake-beam with respectto the wheels of the truck, while at the same time positively preventing the accidental or unintentional detachment or disen agement of the brake beam, and parts carrie thereby, when the brake beam is 'in its normal operative position. A further object is to provide a brake hanger which maybe detached s`o as "l y ti'v@ posi tion, and by this m'ens the acci vvvvhieh-follow thedropping or displacement ."ob'ect relates to the' means which 'are ing'the hanger, and improved means the hanger from the4 to release the 'brake beam 'only when the hanger is Adisplaced.from its normal operative posit-ion, whichdisplacement is' normally prevented by parts of the car truck.

.Stillaiother object is to provide-an in iproved: form of bracket or lug for suppofis. r connecting the hanger to the-bracket. This connecting means ositively prevents thedetachment ofthe anger `from the bracket when the brake-beam is in its normal opera` ents of the brake beam are avoided. A further vi Aed for permittin the ready remove of racket, when desired'.

These and other ob'ects ofthe invention will be more specificaliy set forth in connecconvivial the follow-ing Specification, takt-.n

Fig. 15 is a perspective .view of the con Auecting pin used in connection with the form '8-5 of the invention illustrated .in 'Figs 13 In the drawings I have illustrated my invention in"con'nectioxi' with 'a well-known' orm of car'truck having the side frame 20,

comprising the upper' arch bar 20%, lower truck bolster 21 hasithe end'portion thereof mounted .between the side-'columns pf t-he vside lframe, 'and the lower arch bar supports the sprin plank 22. Thebrakesbea'm-QE, of channel orm, has mounted thereonand se cured thereto the brake head24, which has ixedltherein'a brake-'shoe 25 ada ted to'y coact with the periphery. of the car w eel- 26,

point'preferably a dj scent-the junction' of the side' column 20- and upperf archbar' -20s its foi-med Aintegrally withthe sidefframe.' This i Abracket' comprises a ange or plate 28f, wh'ich is preferably inclined -iipwaljdlyv 'fthehorizontal toward the adjacentend offthe side frame, and formed tegm-llywth plate or fiange is the upwardly extend the this, ub is provided with an aperture 30 exupper arch bar a. depending arm or hub 29 1s formed integrally with the under side of late 28IL at the outer end thereof, and

tending parallel to the axis of the WheelV 26. The aperture is adapted to receive-the connecting pin 31 which formsa bearingfor the brake hanger 32. The brake hanger .in this form of the invention is substantially U.-shaped, comprising two parallel arms 32a and a transverse member 32b which is adaptthrou hthe a erture 24:n4 in the brake` hea and um a), caring therefor. Each of the arms of the hanger are provided .witlr enlarged upper extremities 32, which are provided with apertures 32" adapted to receive .and be journaled on the projecting extremities ofthe connecting pin 31..

,Thc connecting pin has formed integrally therewith a central elongated lug 31 and two 'end ,lugs 31?, all` of said lugs being of substantially U-shape'in cross section,'and being arranged'in alinement with each other pxlpjecting transversely to the axis of the pin.

e depending hub 29 of the bracket is pro- V vided with a` transverse slot or notch 29, Y which communicates with the aperture 30, preferably on the upper side thereof, substantially -in the `same plane as the rib 28".

The enlarged extremities 32 of Vthe hanger I 32 are sim' arly provided with transverse Y the slots 'or notches p32, which communicate with the apertures 32, preferably in a plane lyingtransversely to thefplane of the arms 32.

The slots or notches 29*v and-32 are'of similar size,':and oflsubstantially the same contoniv as, the lugs 3l and ,31b projectin A from Aas to receive and be somewhat closely fitted by the enlarged hub .portions 32 of the hanger. When the hanger is in the position Villustrated by dotted lines 32' in Fig. 1, and

the pin 31 has been inserted to such position that the spaces between the lugs 31l and 31 register withV the Vvhub portions 32 E of the hanger, vthe hanger maybe lowered to the y position shown in Fig. l, for instance, when the notches 32 will pass out of registry with the lugs 31", whereby the hanger will be retained 1n pivotal connection with the bracket.

c The lug 31* will then be seated in the notch or slot 29, so that the pin will be maintained in non-rotative en a ement with the bracket, but the hanger wi ave a rotative engageerger/tin `./pin, so'thatwhenthe anger ment with the pin 31, and will be permitted to move angularly in its normal position through a space determined by the .usual worki ng limits of the brake and brake beam. It Willbe observed that a considerable. angular movement of the hanger from I.the normal position shown in Fig. 1 is necessaryto bring the notches 32 and 29IL in registry, so as to permit the removal of the pin. In this construction the slots 32 are directed toward the end of the side frame and toward the wheel 2G, so that after the wheel-and the axle upon which it is mounted have beenv assembled on tli'e truc-k, the wheel will pre-l vent the brake shoe and brakebeaan from being moved to such position as to permit removal of the pin and detachment of the hanger. It will be observed that the s ring plank 22, carried by the side frame an also the truck bolster, will prevent angular move-1 ment of the brake hanger irLthe er dire@ tion, so as tobring the notches or slots 29* and 32a into alinement.

A In the form of the invention illustrated in Figs. 4, 5, and 6 the hanger bracket 35 is of substantially/thc same form as the bracket 28 previously described, except that the depending hub ortion 36 thereof is provided with a'vertically extending slot-36, which is adapted t0 receive the head 37l bf the hanger 37, which,,in this construction, is in the form of a loop having a transverse arm 37 ada ed to form a bearing for the bralge head, means of whiclrthe brake beam is carri The head 37 of the hanger 37 is provided with a circular aperture 37, having a U- shalped slot 37 communicating therewith in a anc transverse to the plane of the hanger. hen the head 37 is placed in the slot 36L of the head 36, the aperture 37 andslot37 are adapted to register with the similar ertures and notches .36J formed through oppositely disposed portions of the head 436 parallel to the longitudinal axis of the racket 35'. A cylindrical connecting pin'38 lOl is then adapted to be passed through the alining apertures and notches of the bracketand, hanger, this pin being provided with transversely pro1ecting U-shaped lugs 38',

which arespaced apart a distance substantially equal tothe width of the slot 36", so that when the pin is passed into position the central ortion thereof will form a. bearing for the liead 37 of the hanger, and the lugs 38 will engagethe corresponding notches 1n the hub'36, so vas to fix the pin in non-ro- "tative4 engagement with *respect to the p bracket. It will, ofcourse, be understood that with this form of the invention, also,

thc notches or slots in the head 36 are arranged to be out of, alinement with the f faiseur-1n comme 3" l0;n communication with thebore 41. The
